IMPROVEMENT lN CAR-WHEELS.

Specification forming part of Letters Patent No. 46,145, dated January31, 1865.

To all whom it may concern Be it known that I, SAMUEL J SEELY, of

New York city, in the State of New York, have invented a new and usefulImprovement in Railroad-Oar Wheels, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, which make part of this specification, and in which- Figure 1represents a side view of my improved car-wheel; Fig. 2, a sectionthrough the same at the line 1 1 of Fig. 1; Fig. 3, a section at theline 2 2 of the same figure; Fig. 4, a side view of the hub, one of thecorrugated side plates, and the central wooden disk detached; Fig. 5, anedge view of the same, Fig. 6, a face view of the central disk; Fig. 7,an edge view of the same; Fig. 8, a face view of one of the corrugatedside plates; Fig. 9, an edge view of the same; Fig. 10, an edge View ofthe hub; Fig. 11, a face view of the same; Fig. 12, a similar view ofthe ring, and Fig. 13 an edge view of the same.

It is the object of my invention to produce a strong, light, cheap, anddurable car-wheel, and ne tha-t will run with comparative silence; andto these ends my improvement consists in combining a cast metal hub witha metallic rim by corrugated metal disks, substantiall y in the mannerhereinafter described.

I cast a hub, A, of iron, wide enough for aproper and secure attachmentto the axle, and with a central flange, 01, upon which a wooden diskfits, and to which the corrugated face-plates U are bolted. This diskand the face-plates connect the hub with the rim B of the wheel. Thisrim may be cast in the usual form on its face, which may be chilled, ifdesired, and has an internal projecting rib, b, in the center of itswidth, or nearly so. The exterior surface of the rim may, if desired, beturned smooth to receive a shrunk tine of wrought-iron. or steel, withany form of flange desired, so as to match any specified rail. The rimmay also be formed of rolled wrought-iron, having an internal rib, andbe bent to the form desired and welded, but of whatever material, andhowever made, must be strong enough to support the corrugated disks, theedges of which are bolted or riveted to it. Theface-plates C may be madein one piece or in sections of wrought metal corrugated radially fromthe hub in any wellknown way. I prefer, however, to strike them up bymeans of dies and punches, because when thus' made their projections anddepressions will always register truly, whether the disks be formed hotor cold; and when thus accurately formed their projections anddepressions occupy such a relation to each other as to adapt them to anydesired thickness of flange, either upon the hub or rim. When desired,the face-plates may even be made of cast or malleable iron.

' A disk, D, of wood, is'interposed between the faceplates, and extendsfrom the flange of thehub to the inner flange of the rim. The faceplates and disks are firmly united by through-bolts or rivets, and theprojecting edges of the'faceplates are similarly united to the flangesof the hub and rim, as shown in the drawings. In order .to deaden thesound and to prevent jarring the wheel, a ring or cushion, o, of rubber,may be interposed both between the hub and disk and the disk and rim, asshown in the drawings. Spokes may be used, if preferred, in place of adisk, in which case cushions of rubber may be interposed between theirends and the hub and flange respectively. The wooden disk or bars serveto keep the disks the proper distance apart, render them rigid, equalizethe strain upon them,and prevent the sound incident to metalwheels.Moreover, by relieving the jar of the wheel, they thus prevent aninjurious molecular change in the metal.

Having thus described my improved carwheel, what I claim therein as new,and desire to secure by Letters Patent, is-

1. The combination of the flanged hub with the flanged rim, by means ofthe corrugated face-plates, substantially in the manner described, forthe purposes set forth.

2. The wooden disk arranged between the rim,the hub, and theface-plates, substantially as and for the purposes described.

In testimony whereof 1 have hereunto subscribed my name.
